Abstract

The genus Phlugiolopsis Zeuner, 1940 is considered: its brief comparison with some similar genera is given, and its subgeneric composition is discussed. This genus is tentatively subdivided into two subgenera: Phlugiolopsis s. str. with three possible species; the subgenus Omkoiana Sänger et Helfert, 2002, stat. nov. with all the other species of this genus including three “subgenera” with unclear status (Longiloba Bian et Shi, 2018; Tribranchis Bian et Shi, 2018; Uncinata Bian et Shi, 2018). Two new species, Ph. (O.) trilobulata sp. nov. with three lobes on the male cercus and Ph. (O.) bilobulata sp. nov. with two such lobes, are described from Vietnam and Indonesia, respectively; these species additionally differ from each other in the male genital plate with specialized apical hooks (Ph. trilobulata sp. nov.) or with a slightly bilobate apex (Ph. bilobulata sp. nov.). From the other congeners, these species are distinguished by the same characters as well as some other features connected mainly with shape of the male cercal lobes and of the female genital plate.
